Differential LVPECL/LVECL/HSTL Receiver/Drivers

Part Number	Status
MAX9321	Active: In Production.
MAX9321A	Active: In Production. See Ordering Information for details.

The MAX9321/MAX9321A are low-skew differential receiver/drivers designed for clock and data distribution. The differential input can be adapted to accept a single-ended input by connecting the on-chip V_BB supply to an input as a reference voltage.

The MAX9321/MAX9321A feature ultra-low propagation delay (172ps) and part-to-part skew (20ps) with 24mA maximum supply current, making these devices ideal for clock buffering or repeating. For interfacing to differential HSTL and LVPECL signals, these devices operate over a +2.25V to +3.8V supply range, allowing high-performance clock and data distribution in systems with a nominal +2.5V or +3.3V supply. For differential LVECL operation, these devices operate from a -2.25V to -3.8V supply. Multiple pinouts are provided to simplify routing across a backplane to either side of a double-sided board.

Both devices are offered in space-saving 8-pin SOT23, SO, and µMAX packages.
